Title: Cleaning equipment
IPC: A47L13/58
Filed: 1988-10-05
Granted: 1993-03-24
Abstract: Cleaning equipment comprises a container 1 from which cleaning liquid 2 is taken, and to which the liquid is returned after it has been used for dirt removal. The container 1 is provided with a dirt trap comprising a dirt-receiving element 3 of mat or pad-like form which is positioned in the container 1 to receive dirt settling under gravity from the contained liquid 2. The dirt which settles out collects in, or alternatively passes through so as to be trapped below, the element 3. The form and structure of the element 3 is such that disturbance of the liquid 2 in the container 1 cannot wash the collected dirt back out into the main body of liquid 2 from, or through, the element 3 to any significant extent.

Abstract: The process centres a pilot (11) which is inserted into a valve guide (25) of a valve seat (24) to be machined and serves therein as a pilot arbor (11) for a form turning tool. The pilot (11), mounted by means of a pivot ball (7) so as to be pivotable on all sides between two clamping shells (6) and displaceably held by the latter between two clamping plates (5), is centred in the valve guide (25) by electronically controlled drive means. For this purpose, it is moved by the drive means by horizontal displacement of the clamping shells (6) in two intersecting directions. The clamping shells (6) are moved one after the other into their two end positions of their displacement range. The displacement path in between is measured electronically. The drive means accordingly move the clamping shells (6) into the electronically calculated centre position of the two measured displacement ranges.

Abstract: In a very small hinged-armature relay of the printed-circuit board relay type, with a dual-in-line connector layout, which relay must be designed for a very high number of operations, the problem exists of designing the armature return spring such that it can withstand the number of operations without any risk of fracture. This problem is solved in the case of the present relay such that the leaf spring, which is connected in a positively locking manner to the limbs of the U-shaped armature (13), and which acts as a return spring, runs approximately parallel to the said limbs and is connected in a force-fitting manner to the coil body (10) forming the relay structure, in contrast to the normal fixing on the corresponding limbs of the E-shaped magnetic yoke (12). In this way, the spring can have a length which is at least equal to the length of the limbs of the armature. In order to simplify production and assembly, the leaf springs of the individual limbs are connected via a lateral web to a single-piece, H-shaped spring (14).

Abstract: This invention concerns, in brief, means of and devices for measuring the flow rate of liquids, as well as equipment for controlling the spray patterns of farm sprayers in which measurements of flow rate according to the invention are included. The liquid to be measured is led into a measuring cylinder (8) whereby the level of the liquid in the measuring cylinder provides a measure of the flow rate. By keeping the level (9) constant by means of level sensors (10) and a control unit (12), together with a pump (12) governed by the control unit, the liquid is pumped through a flow meter (14) which, without losses, gives a rapid and reliable measurement of the flow rate. This method of measuring the flow rate is utilized in equipment consisting of a trolley, which runs on a track and which collects in a collection channel the spray emitted from nozzles. The part of the spray liquid which is caught by the collection channel is measured with regard to flow rate and these measurements are done either stepwise or continuously along the nozzle boom, whereby a total picture of the sprayer's condition is obtained.

Title: Device for contactless detection of overheated parts on passing railway vehicles
IPC: B61K9/06
Filed: 1989-10-27
Granted: 1993-09-01
Abstract: A device for the contactless detection of overheated parts, such as, for example, axle bearings, brakes, wheel tyres, on passing rail vehicles is described. The device has a sensor (2), which is provided with an infrared optical system, and an infrared detector (12) with subsequent electronics and evaluation circuit (15) connected downstream. The device is characterised in that the sensor with the infrared optical system (3) on the one hand and the infrared detector (12) with subsequent electronics on the other are arranged spatially separated from one another and in that in order to pass on the infrared beams from the optical system to the detector at least one fibre which guides the infrared light in the wavelength range of approximately 2-12 micrometers is provided. In a preferred embodiment, a plurality of fibres (16, 17, 18) which run parallel to one another are used, the sensor-side light injection surfaces of which are directed towards different heat targets and whose detector-side light emergence surfaces have a scanner element (19, 20) opposite them which successively guides the beams which emerge from these emergence surfaces onto the detector in a constantly repeating fashion. An assignment electronic system (25) connected downstream receives an item of information relating to the current position of the scanner element (19, 20) and assigns the individual temperature-analogous electrical signals unambiguously to the respective fibres (16, 17, 18). <IMAGE>

Title: Backflow preventer for sanitary systems, especially for installation in a sanitary fitting
IPC: E03C1/10
Filed: 1989-11-02
Granted: 1992-01-29
Abstract: A pipe interrupter, which is particularly suitable for installation in a sanitary fitting, comprises in a housing a chamber, into which a water-supply passage, a water-discharge passage and a ventilation path open. Located in the chamber is a rolling membrane, which is fixed at the peripheral region. Normally, thus as long as there is no reduced pressure in the supply passage, the rolling membrane bears in the central region against the opening aperture of the ventilation path in the chamber, so that on the one hand no atmospheric air may enter and on the other hand no water may escape. However, if reduced pressure occurs in the pipe system, which is connected to the supply passage, then the rolling membrane overturns so that now on the opposite side of the central region it closes the opening point of the supply passage into the chamber. On the other side, a ventilation path to the chamber is exposed. This ventilation path continues by way of a through-flow opening in the edge region of the rolling membrane towards the discharge passage. In this way, water can no longer flow back into the supply passage and into the pipe system connected thereto; on the other hand, the water-ways following the chamber are ventilated.

Title: A spreader bar apparatus
Inventor: CROUSE JERE WILMOT
IPC: B65H23/32
Filed: 1989-10-12
Granted: 1995-04-19
Abstract: A spreader bar apparatus (10A) is disclosed for separating slit portions (30-34) of a web (WA). The apparatus includes a first spreader bar (12A) which extends in a cross-machine direction (CD) relative to the web. The first spreader bar (12A) is bowed relative to the slit portions (30-34) such that the slit portions are separated axially relative to each other when the slit portions (30-34) are guided around the first spreader bar (12A). A second spreader bar (14A) is disposed downstream relative to the first bar (12A) and extends in a cross-machine direction (CD) relative to the web (WA) for guiding the separated slit portions (40-44). The second bar (14A) is bowed relative to the separated slit portions (40-44) such that each of the slit portions (50-54) disposed downstream relative to the second bar (14A) is disposed parallel to each other. A first and a second porous layer are connected to the first and second bars (12A, 14A) respectively such that when the bars are connected to a source of pressurized air, air flows through the bars (12A, 14A) and the porous layers towards the slit portions(30-34, 40-44) for generating respectively a first and second air cushion. The cushions reduce the frictional resistance between the moving slit portions (30-34, 40-44) and the bars (12A, 14A). Additionally, the air cushions reduce the noise level caused by movement of the slit portions when the slit portions move relative to and are guided by the spreader bars (12A, 14A).
